To, all -wzom 'it 'may concern:

. Be it known that l, HERBERT J. LEIGH- TON, of'Syracusain `he county of Onondaga and State of New York, have invented acertain new and useful Internal-Combustion Engine, of which hefollowing is a speciiication.v 'Y

, My invention relates to internal-combua A tion engines and has for its object the production of' an ignition-controlling mechan- 'isin for such engines which is particularly simple' in construction and practical and etfective in use; and-to this'. end, it consists in the devices acombinations hereinafter set forth and claimed` l In describing this invention, reference is fhad to the accompanyingdrawing in which like characters designate corresponding parts yin all the' views.

AFigure "iv is an elevationjo'f a preerred construction of'my engine, the details 'not 'pertainiii tothe present invention being omitgreater' portion lof the ignition-controlling mechanism shown in Fig. 1, and' contiguous partsof the driving shaft and a supplemental the engine.` Fig. 3 is a vertical sectional lviewtaken on' line 3v vdriven vmember and D, the crank-casing of the illustrated preferred construction of my y lengine, all of Whi'cli parts may be of any suit- 5 v able form, size and construction. The driv ing member B is connected in lany desirable.

manner to the piston of the engine, and is here lshown as the driving or crank shaft .of the-engine, and the driven member C is here illustratedas having a toothed periphery and asy mounted on a supplemental shaft 4c connected by'a cam or eccentric c', a vertically reciprocating varm o2, and a rock-shaft of to means, for producing the ignitions said means including a movable terminal c4. 50

It will be obvious, hoWever,-to thoseslrilled in the art,`

- that anyfsuitable means may be used for producmgthe ignitions and iorconn-eeting the .driven'ineinber or gear C to said means.

. i ,Therdriven member or. gear C is preferably. connected 'tb the crank-shaft or driving nieini ber byvmeans for actuating said driven 2 an edge elevation of the member and for moving the same relatively to the driving member, and thereby varying' the high point of the cam or eccentrico relatively to a given point on the crank-shaft, and changing the tinie lof the ignitions with respect to the position of the piston. Said means is here shown asa pinion b fixed to the 4driving member B, a pair of gears d d connected to- 4 getlierand connected, respectively, to upper surfaces of the driven member C andthe pinion b, and -nieans for supporting and adjusting the gears and holding the same in their adjusted position.

trated as relatively proportioned for causing the driven member C to rotate at the same speed as the driving member B, but it is obvious that said parts may be of such size, as to cause the driven member C to make an)T desired predetermined movement or number. of revolutions for each revolution of the driving member. c j

The means for supporting and 'adjusting the gears d dv and holding the same in their adjusted position, is here shown as consisting of a support c carrying spindles for said gears at opposite portions thereof, connecting parts or arms e. e2 movable, respectively, relativelyto the driven and driving members about the crank-shaft B and the supplemen-` The driven member. C,.` the pinion b and the. gears (l d are here illustalshaft c and looselyT ournaled on the spindles; of the gears CZ d,'an arm e3 forming a continuation of one of the connecting parts and extending u Wardly along the cylinder of the engine an( movable along a segment or guide e4, i'iXed to the main part of the engine and fastening means e5 for securing the 'i arm e3 to the segment or guide e4. The driving andr driven gears l) and C, the interposed gears d d', the shaft c, and the reciprocating arm c2 are located Wholly outside of the crank-casing D and the part e is in the form vof a housing which both supports and protects the gears I d. As best seen in Figs. 1

and 2 the shaft c is arranged parallel to, and

above and at one side of the crankshaft B, and the gears fl d/ are arranged above the crank-shaft. Such arrangement of the l,parts c, d d is particularly compact and efficient and does not materially increase thesize of the engin. 7Vhcn said arm e3 is rocked backivardl or forwardly, the support e, the

connecting parts e e2 and the gears d d i'nove relatively to the driving and driven members B C andthereby rotatesaid driven member relatively to the driving member a greater' difstance'j'th'an the gear d isl rotated-rela- -t'velyto .said driving nieniber, Aas indicated -in- Fig. 4, in which figure pr'edetermined concated, respectively, i by the ordinals- 1 2 3.

'Ilier-,Inoveinent'of-thesiippert e, just described, varies the .time ,ofthe ignitions with respectgto. the position of th'e piston of the4 engine, and i-naytakeplace during the operatio n o,f said ,engineffor in'ay be utilized to lstart or operate the engine in' either direc'-l tion.

he construction and ,operation of my in- .ternakc'oinbustion engine' will now be readily -understood alpen-'reference to the foregoing AAdescription and the accompanying drawing,

. tion engine having .the construction and rit will be obvious .to those skilledin the ait'tliat inore or less-change may be inade in f yand iarrangeinent of its parts, and particularly of its ineans for con- 4trolling the igiiitions, without departing from the spirit of my invention.

Havi i0 thus fully described Iny invention, i

what I c aim4 as 'new` and desire to secure by Letters Patent, is

-. In combination in an internalconibus crank-shaft' projecting outside of said casing, lanfigniting mechanism including a movable a' crank-casing and a ranged outside of the cran -casing parallel to the crank-shaft, a' cani on the shaft outside of the crank-casingand connectedA to the reciprocating rod, and ineans. for rotating the cani frein the crank-shaftyandgalsofor vary'-y ing the high point of said oain relativelyto a given oint on the crankfshat, said means'.

comprising a driven gear xed on the caml signed niy naine in the presenceof two attesting witnesses, at Syracuse, in Vthe county of Onondaga, in the State vof New York, tli's 27th day of February, 1902.
